A water temperature of 40C is a common setting for washing machines, typically used for synthetic fabrics, mixed fiber garments, and colored items. This temperature setting offers a balance between effective cleaning and fabric care, preventing shrinkage or damage that might occur at higher temperatures.
Washing clothes at this moderate temperature helps preserve the vibrancy of colors, maintains the integrity of synthetic fibers, and effectively removes everyday dirt and grime. Historically, advancements in detergent technology have allowed for effective cleaning at lower temperatures, contributing to energy savings and reduced environmental impact. This temperature setting is often recommended as a standard for regular laundry care, striking a compromise between cleanliness and fabric longevity.
